Diet part 4 - Eating enough calorie wise

If you want to gain muscle, you should eat more of everything.

If you want to lose weight, you should eat less of everything.

And you can't choose both, at first you should focus on what's advised (if you're skinny eat more, if you're fat eat less) and then decide whatever you want to do.

Bulking (gaining muscle) : If you want to gain weight, try eating (16-18 x [bodyweight in lbs] ) calories every day, for as long as you can.

Gaining 3-5 pounds per month would be your target, gaining any more than that wouldn't help you much as it's mostly fat.

And if you say that you eat a lot and you don't gain any weight, you're not eating enough, simple as that.

Cutting (losing fat) : If you want to lose fat, try eating (10-12 x [bodyweight in lbs]) calories per day and keep that protein intake as high as you can.

You need to keep exercising while cutting, otherwise it will not be effective, it will be uncomfortable but you need to bare with it for the results.

You should not resort to surgery as it's not safe, there are huge risks compared to exercising where you can lose all the weigh you want with no risks at all.

If you can't gain weight or lose weight, you're most likely not counting well, try to adjust the number of calories the next day.

Gaining more than 1 lbs per week is not recommended as what you gain after that is mostly fat also losing more than 1 lb per week is not recommended either as you'll be starting to lose muscle.

There are many ways of counting calories, there are some great calculators out there on the web, I usually use WolframAlpha or Cron-o-meter.

ALSO DON'T FORGET TO EAT AS MUCH VEGETABLES AS YOU CAN!
